What type of equipment are torque wrenches classified as?

Torque wrenches are primarily classified as calibrated tools because they are specifically designed to apply a precise amount of torque to a fastener, like a nut or bolt. This precision is critical in various engineering and construction applications to ensure that the fasteners are tightened to the manufacturer's specifications, preventing issues such as over-tightening or under-tightening.

Calibration is essential for torque wrenches to ensure their accuracy over time; without proper calibration, the tool could give misleading readings and interfere with the integrity of the assembly process. In essence, a calibrated tool is one that has been adjusted to meet a standard measurement, and for a torque wrench, this involves checking and adjusting the torque applied against a known standard.

While it’s true that torque wrenches do have measurement capabilities, particularly in terms of torque applied, their primary function aligns more closely with calibration. They are not classified as cutting tools since they do not cut materials, nor are they purely fastening tools because their focus is on the measurement and application of torque rather than just the act of fastening itself.
